Run crayons through a hot glue gun onto canvas. A design or letter would be cool too. (**Do NOT do this try the other glue gun crayon projects don't put the crayons in your gluegun! use the dryer with them glued to canvas)
for the OCD peeps, spice storage - i like the idea of having chalkboard on top of the jar. I could do this with chalkboard paper & a chalk pen! it would be easier to identify the spices than my current sharpie method.
